r area is stretched by the traction of the fundus inits new position. This is well shown in the accompanying figure, whichis from a frozen section, after Benckiser. Uterine involution is due to atrophy of muscle fibres, following alessened blood supply. This is conceded to be a fact since the re-searches of Sanger and of Dietrich. The pathologic stretching of theanterior, lower area of the uterus increases the normal anemia of theparts and thereby hastens involution, but the weight of the distortedfundus will not permit atrophy of the fibres in their normal relations, inconsequence of which these anterior areas remain elongated. The pres-sure and gentle massage of the- intestines and bladder on this anteriorportion also hasten involution; while, at the same time, involution andatrophy of the posterior areas cannot be synchronous with that of theanterior, because of the reversed relation of the blood and lymph vessels,consequent upon the abnormal position of the uterus. This stasis may

If now we permitted theuterus to assume its normal position early in the puerperium, with itsanterior wall supported by the pubes and abdominal muscles and raisedat times by the bladder, and with its posterior wall pressed upon by theintestines, the normal curve of the cervico-uterine canal would be main-tained, affording free drainage of lochia and clots, thus lessening thedanger of infection; and, at the same time, involution must be uniform,because the factors which produce subinvolution and retro-displace-ments cannot obtain.
